That's right Michael, I think any modeling package that uses the parasolid kernel is strong in this area, If you do a lot of shelling that's fine, if not, there is always a workaround in MoI to get the same result.

Thanks Michael / DannyT - Some of our mould cavities and quite complex and shelling can be a big problem sometimes....and
would be almost impossible to workaround in MoI (at the moment at might add)

I will do more investigation...in the meantime im going to buy MoI now :-)

Cheers,
